Note	This datasheet PDF includes multiple part numbers: STR3A155, STR3A151. Please refer to the document for exact specifications by model.

STR3A100 series are power ICs for switching power supplies, incorporating a power MOSFET and a current mode PWM controller IC in one package.

Current mode PWM control.
Built-in Random Switching function: reduces EMI noise, simplifies EMI filters, and cuts cost by external part reduction.
Built-in Slope Compensation function: avoids subharmonic oscillation.
Built-in Leading Edge Blanking (LEB) function.
Auto Standby function: ▫ Input power, PIN < 10 mW at no load with low power consumption shunt regulator ▫ Normal load operation: PWM switching ▫ Light load operation: Standby mode (Burst osc.
